I have a tremendous amount of static intermittently coming through the speakers, whether the radio is switched on or off. I am told its the amplifier in the luggage compartment in the back. Can it be repaired because i am struggling to find a second hand one.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

Static electricity could be causing the static . It's possible the way they were soldered together That's what I was told so I got sick of the static and gave my old ones away and got another set of speakers. They work fine. Was also told it could be the plug ins for my amp as well not being tight enough.
Assuming it's the monsoon amplifier it's located under the rear deck about 8 inches away from the passenger rear speaker. However unplugging it will kill all the speakers. The only way to properly bypass it is to run all new wires. You maybe able to find another factory amp at a salvage yard.
Warning: Most of the Monsoon head units have a 6V offset, making it incompatible with aftermarket amps.
That means that if too much power is going to the speaker or extraneous signals are being picked up by the wiring, it can come through the speakers as static. Stopping static requires finding and eliminating that extra electricity from transmitting through your speakers.
If you're still hearing distortion, turn down the volume on your amplifier until the distortion goes away. If the volume is too low to be easily heard, the problem may be that your amplifier produces too much power for your speakers to handle or that your amp and speakers have different impedance ratings.
take out the speaker in question and test it.
a 9v battery is good enough to 'burp' it.
if it makes a scratchy noise when you put power to it then you have a short in the voice coil.
Burping a speaker is just a short power up. Don't hold power to it.
Tap it on and off like a music note measure.
A Blaupunkt? Verify that the speakers are connected to the radio. This is simple if they are directly connected, but if they are connected through a power amplifier, then things get a little more complicated. If there is a power amp, then you might want to try connecting a speaker to the radio directly first, to help determine whether the problem is with radio, amp, wiring, or speakers.
More than likely with a 2003, the speakers that cut out are in the door or doors. Do they cut out of both speakers?
If they cut out of one, then you may have an intermittent speaker ( the wire to the cone becomes partially connected)
If both speakers turn off at the same time and you hear NOTHING on all speakers, then you more than likely have an intermittent connection on the radio itself and probably replacement is probably cheaper than fixing the radio.
One more thing Factory radios sometimes have an amplifier in them. Sounds funny but they call the Radio in the dash the Head Unit and the amplifier is buried in the dash. You could have a bad amplifier or a loose power connection to it, but that is very unlikely.
Might be a failing semiconductor component (usually an old transistor) in the amplifier's front end. This caused by the oxidation through the component legs or pin. I usually touch and move each transistor's body to exaggerate the noise. You can research also what kind of noise is it producing- intermittent, static, etc.
hope this helps..
The rear signal is generated and separated internally, if either the processing is not correct or the rear channel amplifier has a problem, you can get this type of behavior. Does the static happen more often at higher volumes or is it purely random? Does changing the volume make the static louder or is it always the same level?
